Which of the following occurs when a cell repairs a double-strand DNA break by the process of nonhomologous end joining? 1.The D

NA sequence at the site of repair is altered by a short addition 2.The original DNA sequence at the site of repair is reconstituted with 100% accuracy. 3.The DNA sequence at the site of repair is altered by a short deletion. 4The DNA sequence at the site of repair matches that of a homologous chromosome. 5The DNA sequence at the site of repair contains a short segment of telomere DNA

Answer:

option 3

Explanation:

In non-homologous end joining, the break ends are directly ligated together without the need for a homologous template unlike the homologous repair. this form of repair uses short homologous sequences of DNA termed microhomologies to direct repair and these microhomologies are seen as single-stranded overhangs found on the ends of double-strand breaks. When the overhangs are perfectly compatible, NHEJ ligates and repair the break. When these overhangs are not compatible, imprecise repair leading to deletion of nucleotides can also occur which is much more common .

Answer:

3.The DNA sequence at the site of repair is altered by a short deletion.  

Explanation:

The nonhomologous end-joining (NHEJ) is a pathway that repairs double-strand breaks in the DNA backbone. The NHEJ pathway directly ligates broken ends in the DNA strands through an enzyme complex that includes DNA protein kinases

Which of the following soil conservation techniques prevents erosion?
nydimaria [60]

All answer choices are correct in soil conservation techniques prevents erosion.

<u>Explanation:</u>

  • Decreasing tillage yields crops to settle in the soil preferably than being broken at the end of a season. The gain of no-till farming is consecutive to the soil structure, which transmits more deposits on the exterior to stand up against severe water and wind situations.
  • With contour ploughing, preferably of seeding crops in straight lines, crops are planted based on the form lines of the area to form stores that save rainwater and lessen top-level soil erosion.
  • Terracing is the habit of producing almost level areas in a hillside area.  Terraces are shielded from erosion by other soil restrictions.

IrinaVladis [17]

Answer:

Thelarche

Explanation:

In females, thelarche represents the start of puberty and as such it marks the beginning of the secondary development of the mammary glands known as breasts. This pubertal development usually occur in females that are between the ages of 8 years and 12 years due to the secretion of hormones such as estrogen.

In this scenario, Emily's body starts to develop secretory glands at the end of the milk ducts in the breasts. Based on the given information, we can say that Emily is most likely to be in the thelarche stage because she is beginning to experience breast budding.
